Talk to Gastroenterologist on Bloating And Swelling Of Stomach

What condition do you think I’m having? It’s been approx more than 7 months I’m suffering. I am having very long chronic bloating issues and it feels heavy and like it’s swelling sensations. I have this problem if I eat and drink. I also have this problem if I eat and drink less, or even if I don’t eat at all. If I will even eat one grape then I will bloat. I burp so much more than normal everyday. I don’t know what to do. My blood tests are normal as well as my stool tests like h-pylori, hba1c, faeces culture standard, coeliac screen, ca125, ferritin, renal profile, liver function test, thyroid, vitamin D, faecal calproctectin are all normal except urine culture test which I was given antibiotics.
